This paper describes the use of daylight coefficients in a computer tool which is based in Monte Carlo backward ray tracing merthod and was developed under the frame of DAYLIGHT- Europe EC Project.
Aris Tsangrassoulis and Mat Santamouris
In  this  paper,  the  parameters  in  a  building  thermal simulation model are tracked, which are subject to modeling uncertainty, i.e. uncertainty arising from commonly applied physical assumptions and simplifications.
Sten de Wit
CA-SIS software has been developed on PC as a tool for engineering offices in their Heating, Ventilating and Air Conditioning studies.
L. Tabary
A large office building has been the object of a detailed feasibility study in order to select the most effective actions for energy saving in space cooling. Actions concerning the modification of building envelope layout, including materials, sha

The physics of moisture transfer is complex and as a result modelling is normally carried out on a macroscopic basis, with empirical coefficients used to simulate the transport process.
Graham H. Galbraith, R. Craig McLean, Jiansong Guo
This paper briefly reviews recent research into the modelling of complex fenestration systems, before presenting some results obtained by the use of a new (developing) simulation model, utilising Monte Carlo Methods and Geometric Optics (ray traci
N.S. Campbell and J.K. Whittle
A controller for heating systems is normally equipped with many facilities to make it flexible and the heating system more cost-efficient. This results in a number of input parameters to be given by the user.
Niclas Björsell
Combined conduction-convection-radiation heat transfer in concrete block walls with one or two cavities is simulated using the CFD code “FIDAP”.
S. Hassid and E. Levinsky
This paper presents a calibration methodology using only two to four weeks of hourly monitored and monthly utility records.
Veronica I. Soebarto
A method to evaluate the energy demand for lighting on an hourly basis is presented. The method is based on a raytracer and a dynamic modelling of the sky’s luminance distribution.
Sebastian Herkel
This article presents a study of a building-equipment coupled system performed at the Gaz de France R & D Division. The commercial building under study is equipped with an air-conditioning installation which includes a gas-fired dual-seJVice a
Frederic Milcent & Laurence Lapenu
A case study is used to introduce a two-step thermal demand calculation for buildings in order to take thermal bridges into consideration.
Romam Rabenseifer
Training new users of simulation programs typically focuses on a single tool–specific techniques for interacting with, creating models, and assessing performance.
Jon W. Hand, Drury B. Crawley
The paper presents an interactive on-line package for calculation of energy and cost demands for residential infiltration and ventilation, with input and output data entry through a web browser. This is a unique tool.
Teresa Forowicz
Passport  Plus  is  a  new  design  tool  for  building thermal analysis which was developed within the European research project PASCOOL of the European Commission.
Mat Santamouris, C.A. Balaras, E. Dascalaki, S. Alvarez, J.F. Coronel, E.G. Rodriguez
Life-cycle design of air conditioning systems requires that plant should be capable of maintaining zone comfort conditions within specified limits, while minimising capital and operating costs.
P.G. Marshallsay and R.E. Luxton
Computer based design aids have much potential to improve the productivity of the design process and provide more confidence in the performance of a building.
William J. Batty & Barbara Swann
Reliable sky luminance models are considered to be conditio sine qua non for accurate computational simulation of daylight distribution in architectural spaces. Toward this end, the paper compares six sky models specifically with regard to their a

This paper investigates the feasibility of using short segments of weather data to simulate annual energy use in buildings.
Larry O. Degelman
A numerical and experimental study is performed to analyze the influence of natural convection on heat transfer in a composite system comprising a porous material heated from below and an air space situated above this.
